11. Peripherals
11.1
Peripheral Identifiers
Table 11-1 defines the Peripheral Identifiers of the SAM3U. A peripheral identifier is required for
the control of the peripheral interrupt with the Nested Vectored Interrupt Controller and for the
control of the peripheral clock with the Power Management Controller.
Note that some Peripherals are always clocked. Please refer to the table below.
